This paper argues that the presence of both profit-based and stock price-based components in compensation contracts provides senior managers the incentive to optimally allocate effort to both implementing previously devised strategies that provide current profits and to formulating new strategies that create shareholder value. If managers are concerned about their reputation and if outcomes of strategy implementation are more informative about their ability than outcomes of strategy formulation, compensation based only on profit will incent managers to boost their reputation by over-allocating effort to strategy implementation. To restore the balance the contract needs to contain some stock-based compensation.

This paper presents a rationale for divestiture consistent with one of the reasons frequently cited by divesting firms, namely, that the firm is undervalued and splitting the firm into its component businesses will make it easier for the market to value the components accurately. When firms are undervalued due to unobservability of divisional cash flows, they may resort to divestiture to raise capital while overvalued firms will use external equity. Diversification thus might result in costly future divestiture. Firms trade off this expected cost of diversification against the benefit of higher levels of cheaper internal capital in deciding the scope of the firm.
